Complete Performance Kit for Your Duramax

Are you on the hunt for a kit that truly has it all? Look no further! This performance kit features a mandrel-bent 4 1/2 inch intake tube designed to maximize airflow, paired with HSP's signature heat shield box. This clever design keeps unwanted hot air from sneaking into your cold air intake. Remember, for every 1-degree rise in intake air temperature, you could lose up to 3 horsepower!

High Flow Turbo Mouthpiece

One of the standout components of this kit is HSP's high flow turbo mouthpiece. This piece allows you to reroute your factory PCV system and remove the factory resonator box, helping to prevent engine oil from gumming up your turbo and intake system. With 3-inch mandrel bent hot side and cold side tubes, along with our max flow Y-bridge and turbo mouthpiece, you can expect impressive performance gains.

Say Goodbye to Factory Failures

If you own a 2011-2016 Duramax, you probably know that the factory hot side intercooler tube is notorious for failure. Its two-piece design and crimped boots often buckle under heat and pressure, leaving you stranded when you least expect it. The factory cold side isn't much better, made of plastic with an unreliable clamping system.

This kit replaces all those failure-prone pipes with high-quality components. You’ll receive our race-proven 5-layer silicone boots, ensuring years of worry-free driving. With our Max flow Y-bridge and turbo mouthpiece, you can anticipate not only better performance but also lower engine temperatures.

Top-Notch Exhaust Management

To help your engine breathe easier, we've included factory replacement 2-inch up pipes. These up pipes are crafted from .120-inch wall tubing and feature the toughest bellows available, ensuring they stand the test of time alongside your truck. Plus, we’ve added a factory replacement coolant tank to keep your engine bay looking sharp.

Stylish and Functional Coolant Tank

Our coolant tank boasts an all-aluminum design and comes equipped with a low coolant sensor. And to add a splash of color to your engine bay, we’ve included an upper coolant tube that also provides extra space for dual pumps, preventing any hose rubbing against the wheel.
